a way to break /etc/master.passwd ?

[weberjn]

I stumbled into this:

root@bill:~ # chsh -s /usr/local/bin/bash
chsh: user information updated

weberjn@bill:/home/weberjn $ sudo chsh -s /usr/local/bin/bash weberjn
chsh: user information updated
weberjn@bill:/home/weberjn $ su - weberjn
You can press Ctrl-D to quickly exit from a shell, or logout from a
login shell.
                -- Konstantinos Konstantinidis <kkonstan@duth.gr>
weberjn@bill:/home/weberjn $ ps -p $$
PID TT  STAT    TIME COMMAND
964  1  S    0:00.12 -su (tcsh)

I could repair this with vipw and modifying the #comment first line

It looks like shell has not changed.
What about bash in the /etc/shells ?

$ su - weberjn

vs

$ su weberjn

?

- is full login, so the changed shell should be active, shouldn't it?

bash is in /etc/shells

Can anybody reproduce the steps above?

I tried again, but now I don't get the effect anymore.
